INVENTOR STORAGE SYSTEM BACKGROUND OF THE DISCLOSURE This invention relates to storage system and, more particularly, to such systems including modular components capable of being assembled in a variety of different configurations.

It has been proposed heretofore in the art to fabricate shelving in such a manner that it can be assembled at the situs of use in varying configurations particularly adapted for the particular use in question. It has been proposed, additionally, to provide such systems which are capable of being disassembled at least partially at the situs of use and, thereafter, either moved to another location or reassembled in a differing configuration particularly adapted to a differing use. One example of such a system is shown in US. Pat. No. 2,577, l 38.

The instant invention concerns itself with systems of this type and the preferred embodiment thereof is particularly adapted for use in the stock room or back room type of environment. Such shelving and storage arrangements have been constructed heretofore primarily of wood and have lacked not only the versatility of the modular-type of system but, additionally, have been rather expensive to fabricate because of the amount of labor involved.

OBJECTS AND SUMMARY OF THE INVENTION It is an object of this invention, thus, to provide a storage system of the general type described which, while affording the advantages of all-wooden shelving insofar as the same relate to structural rigidity, longevity and the like, provides additionally the convenience and versatility of the modular, knock-down type of systems.

It is an object of this invention, more particularly, to provide a system of the type described wherein the various article supporting surfaces, rods and the like may be quickly and easily assembled into any desired configuration and, if desirable at some later date, disassembled and re-assembled in a differing configuration more suitable to the various articles then being stored.

It is an object of this invention, additionally, to provide such a system which is extremely stable and rigid and, yet, which may be easily and quickly assembled or disassembled by nonskilled labor.

It is yet a further object of this invention to provide a system of the type described which may be fabricated and assembled relatively inexpensively and with minimal labor.

These as well as other objects of this invention are accomplished through the provision of an article storage system comprising a series of elongated, load-bearing members adapted to be positioned vertically in space, side-by-side relationship with respect to one another. Each of the members has at least two spaced uprights, each of the uprights having a pair of opposed, spaced surfaces. Each of the surfaces, in turn, have a series of vertically spaced engaging means therealong, each of the engaging means including an upwardly extending tongue-like member. The base portions of the tongue-like members are affixed to the surfaces from which they extend and the upper portions thereof are spaced from such surfaces. Article supporting means are provided which are adapted to be suspended between two of the load-bearing members, the supporting means including at least four spaced tongue-like member engaging means, the spacing between said engaging means, said uprights and said bearing members being such that each of said engaging means on said supporting means is engageable with a tongue-like member on a different of said surfaces.

FIG. 12 is a side-elevational view of the front skirt.

Referring initiallyto FIG. 1, there is illustrated a storage system 10 including two back-to-back sections 10A and 108. Each section includes a series of spaced, elongated, load-bearing members 20 positioned in side-by-side relationship with respect to one another. Each of the load-bearing members 20, as illustrated additionally in FIGS. 2 through 4, comprises a pair of spaced metal uprights 21a and 21b. The uprights include a connecting section 22 having a pair of plate sections 23 extending perpendicularly therefrom in generally U-shaped fashion and are formed, preferably, integrally from suitable metallic stock.

The exterior, opposed surfaces 27 and 27' of the plate sections 23 have formed directly therein through a suitable lancing or die-cutting process a series of vertically spaced, tonguelike members 25. Each of the tongue-like members 25 includes a base section 26 extending away from its surface 27 at an acute angle and thereafter bending upwardly so as to lie generally parallel to but spaced from the surfaces 27 at upper section 28. Upper section 28, as will be noted clearly from FIG. 4, preferably includes a rounded upper edge 35 in the manner illustrated to assist in the installation of a particular system as will become apparent hereinafter.

The resulting configuration provides a space 26 between the upper portion 28 of the tongue-like member and the plane of the surface 27, which space narrows at the base section 26 in converging fashion to form somewhat of a wedging area between the base section 26 and a member overlying the surface 27 as will be discussed hereinafter.

As illustrated in FIGS. 1 and 2, the tongue-like members 25 are spaced preferably relatively close to one another along the uprights 21, the shelves, hanger rods and the like being movable vertically from one to the other to achieve the desired vertical spacing between article supporting members. Ordinarily, of course, the components will be fabricated such that the vertical position of each of the tongue-like members on a particular upright will correspond to one of the tongue-like members on the attached upright as well as upon the remainder of the uprights in the system such that the shelves, hanger rods and the like may be positioned in generally horizontal fashion between any two of the load-bearing members 20 when desired.

As illustrated best in FIG. 4, the tongue-like members are formed preferably by die-cutting or lancing the stock utilized in the fabrication of the upright prior to its being rolled or otherwise formed in its U-shaped configuration. Such a procedure may be accomplished easily, as will be readily appreciated by those skilled in the art and the tongue-like members can be given the desired configuration as illustrated in FIG. 4 with little difficulty and with little fabricating expense.

The two uprights 21a and 21b forming a particular loadbearing member 20 may be maintained in spaced relationship by means of a continuous sheet spacer 30 such as illustrated in FIG. 1, or by means of spaced non-continuous spacers 31 such as are illustrated in FIG. 2 depending upon the desirability of maintaining a solid boundary between vertical rows of shelves. In either case, the wooden spacer is preferably routed as indicated at 32 in FIG. 3 along the edges thereof which are to fit into the interior of the U-shaped uprights 21. Each of the vertical edges of the continuous spacer or barrier 30 or of the spacers 31 will be so routed and the uprights affixed thereto such that the openings in their U-shaped cross section face one another. The uprights may be secured to the filler 30 or spacers 31 by any suitable means such as screws or, altematively, by crimping the edges of the plates 23 to the wood in a manner similar to be described later in conjunction with FIG. 7.

The spacers 30 or 31 will be installed, ordinarily, at, the point of fabrication of the various system components and the load-bearing members 20 or 20' will be shipped to the installation situs in assembled configuration. By following such a procedure, desirable tolerances can be maintained with ease and, the rather flat nature of the members when rotated to a horizontal position presents little shipping problems.

At the situs of installation they may be oriented vertically at the desired locations and, as illustrated in FIG. 1, have conventional sway..braces 33 affixed thereto in crossing fashion as necessary. If desirable, additionally, a screen or other barrier may be affixed to the rear of the units and a top 21 positioned along the upper extremities thereof. In the embodiment illustrated in FIG. l,.of course, two of the load-bearing members have been positioned in aligned relationship with respect to one another along the length of the entire unit and access to the various article storage members so formed is gained from opposite sides of the unit.

Referring now additionally to FIGS. through 8, the shelves 40 include a middle section or panel 41 fonned from wood or metal. In accordance with the preferred embodiment of this invention, this panel is formed from wood and the shelf includes two rigid end supports 42 (FIGS. 5 through 7) or 42' (FIG. 8). Either of the embodiments of the end supports 42, 42' are generally U-shaped in cross section and include a connecting web 43 having legs 44 extending perpendicularly therefrom. Near the base of the legs (adjacent the connecting web 43) at each extremity and on both sides of the rigid members 42 elongated apertures or slots 45 are formed by a suitable punching process. The length of apertures 45 exceeds, preferably, the width of tongue-like members 25 slightly. It has been found, for example, that if the tongue-like members have a width of three-quarters of one inch, the slots 45 should be approximately seven-eighths of one inch in length. With proper vertical spacing of the members 25, this difference in dimension permits not only the installation of the shelves with relative ease but, additionally, allows one or more shelves to be suspended in slanted fashion to retain bulk goods on the shelves in such a manner that they will not tend to fall outwardly into the aisles.

As illustrated specifically in FIG. 10, the instant invention contemplates the penetration or engagement of the tonguelike members 25 through the apertures 45 when the shelf is suspended between four uprights 20. This necessitates, of course, the provision of a space between the connecting web 43 and the ends of the wooden members 41. Such provision is accomplished in the embodiment illustrated in FIGS. 5 through 7 by providing a series of three dimples 46 extending inwardly into the channels a distance such that, when the I channel is slid onto the extremity of the shelf, the dimples will arrest its inward movement at the proper position. The dimples 46, of course, must be offset laterally from the apertures or slots 45 so that they will not foul penetration of the tonguelike members 25. The edges of the rigid members 42 may then be rolled into wood' or fiber shelf member as indicated at 48 in FIG. 7 to secure the rigid end members 42 to the shelving member 41.

Alternatively, as illustrated in FIG. 8, the shelf extremities may be routed as indicated at 47 to receive the rigid members thereover, the dimensions of the routed area being controlled such that the edge of the legs-44 contacts the non-routed portion of the shelf when the proper spacing between web 43 and the shelf extremity is achieved. The rigid members 42 can thereafter be affixed to the wooden members by rolling the edges thereof over as indicated at 48', by screwing or by any other suitable means.

It should be noted that in either of the embodiments illustrated in FIGS. 5 through 8, it is desirable that the finished shelf 40 be as nearly as planar as possible along its entire length which, of course, includes the leg portions 44 of the rigid support members 42 and 42'. Such is accomplished most easily, of course, by the routing procedure illustrated in FIG. 8, although it is possible to sufficiently flatten the leg portions 44 during the rolling process to achieve the desired result.

Referring now additionally to FIG. 9, there is illustrated a hanger rod support 50 suitable for utilization in the system of the instant invention. Support 50 includes a rod-receiving aperture 51 having hanging apertures 52a, 52b, 52c, and 52d in the ends thereof. The vertical spacing between apertures 52a and 520 and apertures 52b and 52d is equal, of course, to the vertical spacing between tongue-like members 25 in the system. The horizontal spacing between apertures 52a and 52b and apertures 52c and 52d, similarly, is equal to the horizontal spacing between the tongue-like members 25 on a particular load-bearing member as utilized in the system. Such dimensions permit the hanger rod support 50 to be suspended between the uprights 21a and 21b of a particular load-bearing member, a similar bracket to be so suspended on the adjacent member, and a pipe or other suitable rod to be suspended therebetween through the apertures 51. The pipe or rod 54 (FIG. 10) may be secured into position through any conventional means such as a cotter key, clip or the like.

The support 50 illustrated in FIG. 9 is particularly adapted for utilization with the load-bearing member 20' illustrated in FIG. 2 since, of course, there will be no room for the pipe to extend through the aperture 51'where a solid spacer such as indicated at 30 in FIG. 1 is utilized. To obviate this particular difficulty, the hanger rod support may be made of a generally boxed configuration (not illustrated) wherein those portions containing the hanging apertures 52 are laterally offset from the rod retaining portion. In such a situation, as will again be readily appreciated by those skilled in the art, sufficient clearance will be provided between the face 53 of the support and the solid spacer 30 to permit the rod 54 to slide into apertures 51 and bear against the edges thereof for support.

Referring now to FIGS. 11 and 12, the instant invention also contemplates the provision of a dress skirt or kick-plate 60 adapted to be suspended on the uprights 21 between the lowest shelves of a particular unit and the floor. The front or dress skirt 60 includes a planar dress member 61 having curled upper and lower edges 62. Extending rearwardly in perpendicular fashion from the extremities of the member 61 are hangers 63, the hangers 63 being provided with hook structures 64.

The assembly of any particular storagesystem necessitates initially, of course, a plan or design as to heights, widths, shelf positions, hanger rod positions, etc. Once such a plan has been completed, the necessary components are either chosen from existing components or purchased. With the components on hand, the installers begin by placing two of the load-bearing members 20 illustrated in FIG. 1 (or 20' as illustrated in FIG. 2) in spaced relationship and suspending one or more shelves, hanger rods or the like therebetween in the manner described. In the case of a shelf such as illustrated in FIG. 10, the unit is slid laterally through an appropriate space 70 (FIG. 2) between the tongue-like members 25 and, when the apertures or receiving slots 45 come into vertical registry with the four tongue-like members 25, shifted downwardly. The shelf in question will then be suspended as indicated in FIG. 10 at each of the four comers thereof. The installation of two such shelves between any two particular load-bearing members 20, of course, will effect stabilization of the unit.

The rigid end members 42 on the shelves, because of their U-shaped configuration, contribute significantly to the structural integrity of the shelf so installed, distributing localized bearing forces on the shelf fairly equally between the four tongue-like members 25. The acute angle of divergence of the base sections 26 of the tongue-like members 25 from the surfaces 27 (see FIG. cause the connecting web 43 of the shelves (or the hanger rod support) to wedge or nest into the base of the members and, thus, prevent direct cantilevered loading of the members 25. Such prevention, of course, also adds markedly to the structural capabilities of the system.

In addition, the rounded edge (FIG. 4) of upper sections 28'of the tongue-like members act as guides when the shelves are installed. Since it is not always easy to see the tongues when a shelf is installed, slots are not always aligned exactly with respect to tongue-like members 25. However, the sloped or curved edges 35 guide the tongues into slots 45 in the event that they are slightly misaligned.

If, for one reason or another, it is desired to create a storage bin or area having a width equal to more than the modular width being utilized, such can be accomplished easily as indicated in FIG. 1 by providing a load-bearing member 20a having a height equal to the combined heights of dress strip 60 and the shelves 40a. The shelves 40a can then be suspended in elevated relationship with respect to the floor between the two regular-height members 20 on either side thereof and the shorter bearing member 20a in the conventional fashion described heretofore.

Once the desired number of load-bearing members 20 have been initially positioned in the desired configuration through the insertion of shelves, hanger bars or the like, the wire netting may be applied to the rear thereof if desired. It may be desirable at this time, additionally, to add the sway braces 33 at regular intervals along the back of the structure to further stabilize the system. At this time, or at a later time, another row of storage shelves 10B behind row 10A as shown in FIG. 1, may be positioned in back-to-back relationship with the partially or completely assembled row 10A so as to minimize necessary aisle space. Upon the addition of the unit 108, suitable dress strips 13 may be added to the exterior ends thereof and, additionally, horizontal braces 11 and 12 added if necessary.

The dress strips 60 are positioned in the manner shown preferably prior to installation of the bottom shelves. This is accomplished, with reference to FIG. 12, by merely sliding them rearwardly over the two lower tongue-like members on adjacent uprights 21a and moving them downwardly such that the portions 65 slide into the space between the tongue-like members in their respective surfaces in a manner similar to that illustrated in conjunction with member in FIG. 10.

After a particular installation has been completed, should it become desirable to change the position of shelves, etc., such may be easily accomplished by merely shifting the shelves upwardly and withdrawing them through the space 70 between the vertically adjacent tongue-like members 25. It should be noted, in this regard, that because apertures or slots 45 are provided on both sides of the members 42, a shelf may be slid into position with either side facing up and with either end facing back. This particular facet of the invention, in addition to aiding in installation of a particular system, permits one side of a shelf to be utilized for articles which might leave debris or the like and the other side of the shelf, when turned over, to be utilized for articles requiring a clean surface.

The instant invention, as noted previously, contemplates the I fabrication of the shelves, uprights, etc., for particular systems in modular widths and lengths so as to permit at least partial if not complete interchangeability of the various components. In the example illustrated in FIG. 1, two of the load-bearing members have sections 14 extending above the top boundary 21 to permit stacking of large articles there'between. While these particular components may contribute to the efficacy of the system in a particular storage environment and, thus, be necessary, they are at least to some extent custom" in nature. Despite the presence of these particular members, however, all of the shelves remain interchangeable, and certain of the load-bearing members may be removed if desirable and replaced with shorter members such as 20A. The system, thus, in short, remains extremely flexible despite the presence of two rather non-standard" components embodied therein.

The rigidity of the present system permits units to be cascaded atop one another. This may be accomplished, for example, by interlocking vertically aligned uprights 21 through the utilization of a channel or the like fitting over the exterior surfaces thereof and containing hooks adapted to engage two or three of the tongueJike members upon each of the vertically aligned uprights. The integrity of the system permits, additionally, the suspension of structural members on the tongues 25 across aisles and the placement atop thereof of suitably supported grating or the like. In this case, of course, the system will become a highly versatile, self-supporting storage system having two or more separate floors of storage area, the grating permitting access to the upper floors.

The selective utilization of metal and wood combinations as described herein adds not only to the structural rigidity of the system but, additionally, to the ease with which the various components may be assembled and disassembled. It reduces significantly, additionally, the amount of fabrication labor involved in the manufacture of the units, thus affording a functionally superior but less expensive unit when compared with all-wood installations.

The system permits, however, the use of all metal shelving which may take the form of a metal shelf surface having a depending skirt about its entire periphery. The vertical measurement of the skirt should exceed the height of tongue-like members 25 and the width thereof should be less than the space 29 at least at the points of engagement. The shelf so constructed may then be supported from the uprights in a fashion similar to that already discussed by nesting the skirt portion thereof between the tongue-like members 25 and the surfaces 27.

While a preferred embodiment of this invention along with minor modifications thereof has been described in detail, it will be readily appreciated by those skilled in the art that other embodiments may be conceived and fabricated without departing from the spirit and scope of this invention.

An article storage system comprising in combination: a plurality of uprights, each of said uprights having a series of upwardly extending tongue-like members, the base portions of said members being affixed to the surfaces from which they extend, the upper portions of said members being spaced from the plane of said surfaces to which they are affixed; shelf means adapted to be suspended from said uprights, said shelf means including an elongated mid-portion having spaced upper and lower support surfaces, each end of which is affixed to a rigid end support extending the width of said mid-portion, said end portions comprising a generally U-shaped channel having a connecting web with leg portions extending generally perpendicular therefrom, said ends of said mid-portion being sandwiched between said leg portions and spaced from said web, said end portions including a pair of spaced openings for receipt of said tongue-like members of said uprights, said tongue-like members extending through said openings and into said space between said connecting web and said mid-portion extremity.
 11. The article storage system according to claim 10 wherein said pair of spaced openings on each of said end supports are positioned adjacent said connecting web in one of said leg portions for receipt of said tongue-like members so that said web portion is in abutment with the surfaces on said uprights from which said tongue-like members extend.
 12. The improved article storage system according to claim 10 wherein said end supports include spacer means offset from said openings to physically prevent the outer extremities of said mid-portions from engaging said web to insure said space for inserting said tongue-like members into said openings.
 13. The improved article storage system according to claim 12 wherein said space means includes a reduced-width section on each extremity of said end portions of said shelf means, the relative length and width of said reduced-width portion and said channel being such that the edges of said leg portions will strike the boundaries between the reduced-width and non-reduced width sections of said mid-portions as said channel is positioned thereon to provide said clearance space.
 14. The improved article storage system according to claim 13 wherein the thickness of said leg portions is approximately equal to the amounts by which the width of said shelf mid-portions are reduced on either side thereof whereby said leg portions forms substantially a planar continuation of the surfaces of said shelf members.
 15. The improved article storage system according to claim 12 wherein said spacer means comprises simple means on the interior surface of said connecting web.
